If the user interface can translate a new RR into either wire format (if
it talks to the back end using DNS QUERY and UPDATE messages) or into
TYPEnnn format (for master files) or some proprietary RDATA blob format,
then no special server support is necessary, provided it conforms to RFC
3597 (handling of unknown RR types).

I don't mean to argue that server support for John's language is
unimportant, just that it isn't a prerequisite.
